To all whom it may concern." I

Be it known that I, Jun-2s EASON, a

citizen of tlieuUhited States, residing at Calhoun city, in the county of Calhoun and State (if-Mississippi, have invented new and usefhl Iinprovements in Switch- Throwing Devices, of which the followingv is a specification.- 1

fl he general object of the invention is to so construct a switch and a carthat the latter can, when it is desired to have the same pass onto a switch, automatically operate't-he'switch'to open it; thus obviating the practice of havin a train-hand 'recede the ear tube switch and set the swltch for the car topass thereonto, and moreover, eliminating the employment of regular switchmen at switches which are frequently 0per ated. 1

Other objects will up ear and be better understood? from; the to lowing descriptiontalien inconnection with the accompanying" drawings, in which, 4

Figure 1 is a plan of the device. Fig. 2 isa'detail side elevation, with the car removed. .Fi 3 is'a detail section a proximately on't he line 3-3 of Fig. 1, s owing bg full lines the position of the parts before switch has been thrown and by dotted lines/the position of the arts after the switchfhas been thrown. Fig. 4is a detail vertical; section taken through onset. the

' track fails and oneither of the lines 44 of Fig. I. i Fig. 5 is a detail section of the lock taken approximately on the line 5-5 of Fig. 1. f

v The switch points 5-5 coact in the ordinary manner with the main rail 7' to direct the car 'wheels-to follow the main track a, or to direct the said car wheels onto the switch 6, The'cross bar 8 which connects the points 5-5 is operated by the lever 9 fnlcrumed on the cross tie 10, and the lever in turn is connected by a link 14- to the crank 11 at the lower endflof the turning bar 12 of theswitch stund 13 which is located to one side of.the main track a. The turning bar 12- has an arm 15 which extends into the path of agblock lfi that may be projected laterally from the car 17. I

The foregoin parts are operated when 'the'car approac es the switch stand and the block 1615 rojected so as to engage with the arm 152 y ,virtne of the movement of the car'the block will now turn the arln,=whereppon the points will be thrown to Specification of Letters Iatent.

open the main track a1 In order to enable the car to pass from the switch 6 onto the mam track a I provide a second switchstand 18'and connect, by means of a link 19.!the 6c crank 20 of the switch stand 18, with abell crank 21', which in turn is connected by means ofa link 22 with the lever 9; The turning arm 23 of theswitch stand 18 has an arm 24 which extendsi'nto the pathof 65 movement of the block 16 on'the car so'that when the said block moves the arm 24, the switch points will be operated threughjth link and lever connections and in'the 'niiiii' ner previously described;

For effectively locking'th e switch oihts against movement during the o'p'erationflo'fswitching a car or train of cars, I preferably provide thetiirning bars of the switch stand with locking arms 25 -25 which are pivotally connected to the locking bars for hmited vertical movement. The rehitive positions of the locking bars and arms 15' and 24 are such that when the said arms 15 and 24 extend outwardly so as to been 8t? gaged by the block on the car, the locking bars 25 25 will be moved to one side ofxthe keepers 2626. -The keepers 2626 have inclined side port-ions 2727 and notches 28-28. The keepers are normally below the 8d pivoted points of the lock arms 25 25.and'

they have rods 2828 which are fnlcrnmed on bearings 29-29, the said rods bein connected together by a st1-1nger30 an der the switch and main track rails end are connected to these elements in any preferred or mechanical manner. The rail 5 of-the switct or siding at oints adjacent oneof the main track rails ported plates 32. The said plates are alt-1f l'tlllfi'ed in the cross tics 10 as shown. in detriil in ig. 4,-whcreby the rail member b"will be depressed under the weight of them! and this downward movement of the said rail- 0!} member 0' will operate to rock the ketipers-i the this-upward movement of the keepers will;-

take place before the car contnctswiththd- 10a arnr which turns the turning arm' of tho switch stand so that when the caroperates to turn the switch stand the loclr'mrin '25 thereof will be turned and over-ride one of the inclined sides 27 of the keeper until it 110 alines with the notch 28, whereupon it will descend into the notch and, thus effectively also connected to arms 31-31 which extenduncar upon spring slip- $11k;

look the switeh points against movement until the car or cars, as the case may be, have passed beyond the spring supported rail section I), whereupon the said rail will move upwardly under the action of its springs and'the keepers moved from engagement with the lock arms. \Vhen the parts are so ..'positioned the switch points will be restored to their original positions under the action of a spring 33 connebted to one end-of the lever 9 and at its opposite end to the angle iron bracket 33 'as clearly shown in Fig. 6 of th drawings. In theirnormal positions the parts are-locked against accidental move ment and until the rails have-been depressed by means of a pin 3i ca 'ied by one of the arms 31 and adapted to enter an opening in the link 14, all of which is shown in Fig? 5.

Although I have shown and described one embodiment of my invention" it is to be understood that I am not to be limited to the specific arrangement and construction of parts since Various changes may be made, within the scope of the appended Clfll'IIlS without departing from the spirlt or sacrificing any of the advantages of the invention.

What I-claim as new is: j 1. In a switchoperat-mg mechanism, the

combinationiwith a. member projecting from a car; of movable switch po nts, mechanism for throwing switch points and arranged to be operated by the member projecting from a car; of movable switch points, mechanism,

for throwing switch points and arranged to be operated by the member projecting from the car, yieldingly supported switch mem-' ber, pivoted keepers, and means connected to the rail members for-moving the'keepers into enqagementwith the throwing mechanism atter the latter has been operated by the member projecting from the car.

In testimony whereof I afiix my signature in presence of two witnesses.
